UNITED STATES To all whom it may concern Be it known that I, HENRY E. RIcHARDs, of Oswego, inthe county of Kendall and State of Illinois, have invented a new and valuable Improvement in Stay-Rollers for Rolling Doors; and I. do hereby declare that the following is a full, clear, and exact description of y the construction and operation of the same, reference being had to the annexed drawings, making a part of this specication, and to the letters and figures of reference marked thereon.

Figure l ot' the drawings is an elevation of the device. Fig. 2 is a vertical sectional view.

This invention has relation to stay-rollers for sliding doors for barns, cars, and other buildings or cases.

The nature of the invention consists in a stay-roller composed of a perforated hub and an inclinedbearing-flan ge on its inner face, its outer face being concave and provided with a recess to receive washers therein, a screwthreaded bolt passing through said hub, and adapted to be secured to a doorsill, as hereinafter shown and described.

In the accompanying drawings, the letter A indicates the sliding door, provided at the top with hangers of' suitable construction, sliding on the guide of the top casing of the door-frame.

B represents the bottom stay-roller, constructed with a short perforated hub portion, a., and an inclined iiange, b, the inner or pro jecting side of which is inclined at an angle approximating forty-tive degrees, so as to bear against the outer angle of the lower edge of the door. This stayroller is journaled on a straight threaded bolt, C, which is screwed into the sill D of the door-frame and forms the bearing of the roll-er. Being straight, there is no tendency to twist under the motion of the door, and the conical bearing ot' the flange allows a free and easy backward-and-forward motion without binding.

The iianged portion of the stay-roller B may be dished or concave upon its outer surface to accommodate the nut or head of the bolt and prevent said nut from projecting. The hub portion is long enough to provide a convenientseat for the door upon the portion b of the roller, and the lower bearing-surface of the door is formed to accommodate this construction.

PATENT OwIcEo HENRY E. RICHARDS, OF OSWEGO, ILLINOIS.

STAY-ROLLER FOR SLIDING DOORS.

SPECIFICATION forming part of Letters Patent No. 228,185, dated June 22, 1880.

Application led October 11, 1879.

The roller` B is slightly concave or recessed on its outer face and provided in said concave tace with a circular depression or recess, o, to receivev the zinc washer t, which iits neatly therein and is covered bythe washer e, immediately under the bolt-head.

The zinc washer is placed in the depression c for the purpose ot' preventing the accu- Inulation of rust in the bearings, and the concavity of the face of the conical flange assists in protecting said bearing from rain.

The object of this invention is to provide, in connection with a sliding door, a stay-roller for its lower edge, which will have its doorbearing b nearly parallel or only slightly inclined to the plane of the door, and its journalbearings at right angles to said plane, this construction and form serving to prevent. the journal frombein g bent or twisted under the swagging movements ot' the door and at the same time to keep the door properly stayed at its lower edge without binding. .l

The convex or bearing flange of this roller is so constructed that there will be but a slight portion of its surface in contact with the lower edge ot' the door, which is not designed to bear on the hub portion a, and may be beveled a little along its outer angle. This arrangement serves materially to lessen friction, and con stitutes a cheap, durable, and simple device` H hereunto subscribed my name in the presence of two witnesses.
